I'm curious as to what you think my best option would be for travelling over six months equipment wise. At the moment I have a Nikon D40 DSLR with a 18-55 kit lens, 50mm 1.8 and 55-200 zoom. I also have an Android S2 smartphone.

I'm keen to take two cameras with me (at least that was my initial thinking) - my DSLR and a smaller camera for casual shots (I was thinking of my smartphone). Then I came across several glowing reviews for the Canon S100 advanced point and shoot.

I'm now toying with whether it is worth buying this camera, whether it is a good choice to replace my D40 - or if it is worth taking alongside a DSLR. I guess I'm basically asking a rehash of the DSLR vs Point and Shoot question, but specifically with regard to travel photography.

If you're really tight on space and need a compact, the S100 would do just fine, you can't go wrong with it.

However, if I were you, I'd put the money towards a newer body (D3100, D3200, even an upgrade to a D5100 or something better), or a new lens. IMO a good lens is the best tool a photographer could have, so consider upgrading your 18-55 to something better, such as a 16-85 or 17-55 2.8. A new prime like the 35mm 1.8 would also be excellent.
